FILING SECTION Filed Dec. 18, 1939 659040 6. @QEUL KH,

Patented July 29, 1941 UNITED STATES PATENT GFFHQE 1 Claim.

This invention relates to piling sections which are used for foundations for buildings and other structures, as well as wharves, piers, coifer-dams and the like, and more particularly to piling sec- .tions comprising concrete-filled shells, which are known in the art as displacement piles.

There are many instances wherein piling sections of the point or end-bearing type are not suitable, and for this purpose there has been developed a series of sections which, when assembled in unitary relationship, provide a metallic shell which is filled with concrete to become a pile of the displacement type. In making piles of this last mentioned type, com- Y ponent parts thereof comprise light-gage metallic sections which interlock at the edges thereof to form a unitary structure.

It is among the objects of the present invention to provide a pile of the displacement type which may be filled with concrete or other ballast, wherein the component parts of the pile unite to form a rigid and durable but lightweight unit.

Another object is the provision ,of a pile of the class described which may be easily and cheaply rolled in simple passes on standard moderate-sized structure mills.

Still another object is the provision of a pile of the displacement type which is made up of a plurality of identical sections or segments which, accordingly, nest compactly for storage before assembly into the unitary structure.

Still another object is the provision of a pile of the type referred to hereinbefore which does not require welding of the component elements or sections.

A further object is to provide a pile having the foregoing advantages and one which is, at the same time, susceptible of easy and rapid assembly.

A still further object is to provide a, pile of the displacement type which may be easily driven.

The invention, then, comprises the features hereinafter fully described and as particularly pointed out in the claim, the following description and the annexed drawing setting forth in detail certain illustrative embodiments of the invention, these being indicative of several of the number of ways in which the principles of the invention may be employed.

In said drawing:

Figure 1 is a fragmentary elevation of the device of the invention, part of which is shown in section;

Figure 2 is an enlarged end view; and

- of the showing of Figure 2.

Referring more particularly to the drawing, the numerals 2, 3 and 4 designate a series of identical sections or segments which are assembled together to form a complete pile which may be subsequently filled with concrete or other ballast. More specifically, each of the sections or segments 2 comprises a pair of substantially straight web members, as at 5 and 6, which are connected together and extend at angles of approximately degrees. As shown in Figure 3, the web member 5 carries on one of its ends a tongue member 8 which comprises a triangular portion, the apex of which lies in a plane at approximately 60 degrees with respect to the axis of the said web. The web 6 carries on its outer end an angularly extending portion I0 which occupies a plane at substantially 60 degrees with respect to the axis of said web; and on the same side of the said web, but spaced inwardly from the angular extension I, there is a thickened extension l2 which terminates in an angular substantially rectangular portion [4. More particularly, the members l0, l2 and M on the outer end of the web 6 provide a groove in which the tongue 8 carried by the next adjacent section or segment is adapted to seat and form an interlock in the manner well known in the art.

While I have shown and described one specific embodiment of the present invention, it will be seen that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of the invention, as defined by the following claim.

I claim:

A hollow pile adapted for the reception of ballast, comprising three assembled sections which are V-shaped in cross-section, the legs of each of the said assembled sections being disposed at angles of approximately a tongue portion on one edge of each of said sections, each of said tongue portions being substantially triangular 1n cross-section with the apex of the triangle at the edge of the section and at an angle of approximately 120 to the major axis of that leg of the section on which it is carried, the other edge of each of said sections having a triangular groove corresponding in shape to the contour of the aforesaid tongue portion, the opening of each of said groove portions being constricted to resist the displacement therefrom of the base of the tongue portion which fits within the same.
